Single Player (skirmish) map generation fails and therefore endless-loops. According to the developer they make use of OpenGL there in some way or the other. (Forum Support Thread), quote: "rendering 2D vectorized shapes and then reading back the resulting graphics buffer" fixed by game update

Observer

Game goes completely black when entering first door in apartment complex. Unplayable

Very low framerate in outside areas, especially while driving. Runs fine in most indoor areas. As of Mesa 17.1+ and Linux kernel 4.11+, the games are generally playable (25+ fps). However, fps is still pitiful relative to Nvidia driver, and still plummets down to the single digits when looking over large areas. Note: SR3 works quite well on RX480 and mesa 17.1.5/LLVM 4.0.1 (70-80FPS in ultra)

Screencheat

Freezes often in the main menu (not always). The sound continues to run. (might be this bug). Note: Works fine with Mesa 17.0 (LLVM 3.9.1) on RX480

Hangs on "screen-changes" from menus to the game and the other way round (map and fights <-> menu/dialog). ALT-TAB out and in again fixes it. Also, stuttering in the 3d/map mode sometimes - workaround: save the game (!?) Fixed in Mesa 17.1.8.
